The discovery of a new “reset” button for the brain’s master biological clock could eventually lead to new treatments for conditions like seasonal affective disorder, reduce the adverse health effects of working the night shift and possibly even treat jet lag.
By disrupting Siberian hamsters' circadian rhythms, Stanford scientists have identified a part of the brain that, when misfiring, inhibits memory. The work could lead to therapies for neurodegenerative diseases in humans.
Casey Diekman, assistant professor of mathematical sciences at New Jersey Institute of Technology (NJIT), is helping to gain greater insight into the biological clock that sets the pace for daily
Salk researchers discover a master gene responsible for sleep and wake cycles, offering hope for a drug that could help reset sleep.
Research led by the University of Warwick’s Systems Biology Centre and Warwick Medical School in collaboration with groups in Nice and Rotterdam has been able to demonstrate how the cycle of cell division in mammalian cells synchronises with the body’s own daily rhythm, its circadian clock.
Patients receiving chemical treatment for cancer often suffer fatigue and body weight loss, two of the most worrying effects of this therapy linked to the alteration of their circadian rhythms.
Fruit flies are pretty predictable when it comes to scheduling their days, with peaks of activity at dawn and dusk and rest times in between.
You've switched to the night shift and your weight skyrockets, or you wake at 7 a.m. on weekdays but sleep until noon on weekends—a social jet lag that can fog your Saturday and Sunday.
A small molecule called VIP, known to synchronize time-keeping neurons in the brain's biological clock, has the startling effect of desynchronizing them at higher dosages, says a research team at Washington University in St. Louis.
